VALVE-LU BRICATOR.

SPECIFICATION forming part of Letters Patent Nov. 706,963, dated August 12, 19102.

Application led April 12, 1902. Serial No. 102,558. (No model.)

To cLZZ whom t may con/cern:

Be it known that I, PETER F. LABAN, a subject of the Emperor of Germany, residing` at Altona-on-the-Elbe, Germany, have invented certain new and useful .Improvements in Valve-Lubricators, of which the following is a full, clear, and exact description.

My invention relates to improvements in valve-lubricators; and the object that I have to in view is the provision of means for automatically supplying a lubricant to the valveseat and other internal parts of the structure during the working or operation of the valve itself.

I 5 According to my invention the lubricatingr liquid is distributed by the movement or action of the valve to different portions of the valve-seat and between the ports in the chest, and at the same time the valve is so constructzo ed that it will always occupy an operative re-Y lation to the point of liquid-feed, so as to be supplied from the latter, notwithstanding the travel or movement of the valve. The lubricant is distributed through the valve- 2 5 chest by open or exposed ducts or channels, so that it may be taken up by the steam and carried to all parts which require lubrication. The improvements involve an exceedingly simple construction of valve and valve-seat, 3o they are reliable and eflicientin the distribution of the lubricant, and they can be embodied at a moderate cost in the manufacture of the valve mechanism.` With these ends in view the invention con- 3 5 sists in the novel construction, arrangement,

and combination of parts, which will be hereinafter fully described, and the actual scope of the invention will be dened by the claims. Reference is to be had to the accompanying 4o drawings, forming part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical transverse section through a valve-chest and an ordinary slidevalve equippedwith lubricating devices as contemplated by my invention. Fig. 2 is a sectional plan View in the plane of the dotted line 2 2 of Fig. l, a part of the valve being broken away in order to more clearly show 5o the valve-seat. Fig. 3 is avertical transverse section taken in the plane of the dotted lino 3 3 of Fig. l. Figs. 4 and 5 are vertical transverse sections illustrating different positions of the slide-valve in order to bring its lubricating feed-passages into registration with 55 dierent distribution-channels in the face of the valve-seat.

In order that others may understand my invention, I have illustrated it as applied to an ordinary locolnotive-engine valve. 6o

The valve-chest is indicated by the numeral 5, and Within it is the ordinary valveseat 6, the same being provided with the inlet-ports 7 7u and the exhaust-port 8. On this valve-seat rests the ordinary slidable valve 9, except that said valve is modified somewhat in its construction in order to embody my improvements. This valve is provided with the usual passages l0 1l, adapted to register with the passages 7 7a and 8 in the regu- 7o lar way, thereby controlling the admission of live steam to the piston-cylinder and the escape of the exhaust-steam from said cylh inder.

One of the improvements contemplated by my invention is a feed-trough 12, the same being formed by cutting a recess inthe top face of the valve 9, which recess extends across the valve on a line close to and parallel with one side edge of the valve, as clearly 8o shown by Figs. l and 2. The valve is furthermore provided with feed-passages 13, any desired number of which may be formed in said valve in order to conduct the lubricant from the feed-trough l2 to the bottom face of 85 the valve. As shown by Figs. 2 and 3 of the drawings, I employ two of these feed-passages, which extend vertically through the valve and which have communication at their upper ends with the feed-trough; but itis 9c evident that the number of these passages may be varied.

The lubricantis supplied in regulated quantities to the interior of the valve-chest by a feed-pipe 14, the latter extending from a reservoir or any other suitable source of supply adapted to be charged or filled with lubricant of a proper kind. This feed-pipe 14 passes through a bushing l5 and has a steam-tight connection with the valve-chest by means of roo an ordinary stuiiing-box 16. The inner portion of this feed-pipe is coupled to or terminates in an overhanging discharge-nozzle 17, the latter being situated within the chamber of the valve-chest 5 and arranged to discharge the liquid directly into the trough l2, which, as before mentioned, is provided inthe upper face of the slidable Valve 9.

x To secure a more uniform and thorough distribution of the lubricant within the valvechest and in order to lubricate the wearingsurfaces of the valve and the valve-seat, I employ the distributing-channels 18 18a and 19 19, These distributing channels are formed in the upper face of the valve-seat 6, and they extend across the valve-chest ou lines parallel with the edges of the steam inlet and exhaust ports. The channel 18 is at one side of the port 7, the channel 19 is between the ports 7a and 8, the channel 18ad lies between the ports 7 and 8, and' the channel 19a lies at one side of the port 7, all as clearly shown by Figs. 2, 4, and 5 of the drawings. The feed-passages 18 are so related to the series o't' distributing-channels that on the adjustment of the valve to the limit of its movement in one direction and to the position shown by Fig. 5 said passages 13 will be brought into registration with the distributing-channels 19 19, The movement of the valve in the opposite direction brings the passages 13 into registration with the other pair of distributing channels 18 18a, as shown by Fig. 4. From thisv description it will be seen that the distributing-passages in the valve alternately register with one pair or the other of the distributing-channels in the valve-seat, and thus the lubricant which is contained in the trough 12 of the valve will be supplied at regular intervals to the distributing-channels.- The 1ubricant may be fed continuously to the trough in the valve, notwithstanding the movement of the latter, because the valve slides in a path below the nozzle 17, whereby said nozzle may deliver the lubricant at all times to the trough of the valve. The lubricant which is supplied to the distributing-channels by the operation or movement of the valve is adapted to overiiow these channels and to spread itself over the engaging faces of the valve-seat and the valve, thereby thoroughly lubricating the contacting surfaces which are most exposed to friction and wear. Furthermore, the lubricant which is contained in the distributing devices of the valve and the valve-seat is exposed to the action of the steam which is supplied to and exhausted from the pistoncylinder, and some of the lubricant will be taken up by the steam, so as to be carried into the cylinder, thereby lubricating the working parts of the engine.

, Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A valve-lubricator, comprising a series of distributing-channels in the exposed face of the valve-seat and adjacent to the steamports therein, a feed-trough in an exposed part of the Valve, distributing passages formed in the valve so as to communicate at all times with the feed-trough and adapted to register with diferent distributing-channels on the movement of the valve, and means for supplying lubricant to said trough.

2. A valve-lubricator, comprising a valveseat having parallel distributing-channels in the exposed surface thereof and between the series of ports, a valve having in its exposed face a trough and also provided with transverse channels which are normally in communication with said trough, said transverse channels arranged on the movement of the valve to register with diiferent distributingchannels in the face of the valve-seat, and

means for supplying lubricant to the distributing-trough.

3. A valve-lubricator comprising a valveseat having distributing-channels in its exposed face and between the ports therein, a valve provided in its top face with a transverse trough, vertical passages in said valve, said passages communicating normally with the feed-trough and adapted to register with diiferent distributing-channels on the movement of the valve, a feed-pipe having a nozzle disposed in overhanging relation to the feed-trough and adapted to deliver lubricant thereto at all points in the movement of the Valve, and means for making a steam-tight connection between the feed-pipe and the valve-chest.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

PETER F. LABAN.
